410 Mr. T. V. Wollaston on Madeiran Coleoptera. 



subgloboso, valde convexo, scabroso, necnon antice mucronibus 

 fortiter asperato, ad basin foveolis duabus mediis impresso ; elytris 

 ubique confertim punctatis (haud striatis), ad apicem integris ; 

 antennis longiusculis, robustis.

R. rather larger and broader than the common R. pusilla, but 

 proportkmably not quite so long; a little darker (or more 

 piceous), and nearly opake. Prothorax much larger and more 

 globose than in that insect, being exceedingly convex, wider 

 and more roughened in front, and with two deep, rounded 

 foveae or depressions (separated only by a narrow, rudimentary 

 dorsal line) in the centre behind. Elytra uniformly and closely 

 punctured all over, the punctures being much smaller and 

 more numerous than those of the R, pusilla, and without any 

 tendency to be arranged either in striae or longitudinal rows ; 

 rounded and entire at the apex, where there is no appearance of 

 an oblique truncation. Antenna a little paler than the rest of 

 the surface, and rather longer and more robust than in the R. 

 pusilla. 



The eight specimens from which the above description has 

 been compiled were taken by Mr. M. Park in Funchal, and, as 

 he believes, in company with the Ade Una f armaria, in a cask of 

 American (?) flour which had remained upwards of a year in the 

 Custom-House, and had become bad. Hence, like the Adelina, 

 it is evident that the present beetle cannot be strictly regarded 

 as Madeiran ; nevertheless, since by such modes of importation 

 species become gradually naturalized, it seems desirable that all 

 introductions should at any rate be admitted into our Catalogue, 

 as serving to point out at what period their importation first 

 took place. In the present instance, however, it appears highly 

 probable that neither of the insects alluded to has as yet been 

 described ; which, if it be true, affords an additional reason for 

 now characterizing them.
